Allowed memory size of xxx bytes exhausted in current latest-container

[pfaelzerchen]

After upgrading my docker-setup to the current latest-container from the 21-branch some hours ago, I got the following error messages:

docker exec nextcloud su - www-data -s /bin/bash -c 'php -f /var/www/html/cron.php'

Fatal error: Allowed memory size of 2097152 bytes exhausted (tried to allocate 438272 bytes) in /var/www/html/3rdparty/composer/autoload_real.php on line 37

This happens basically with every php-command, e.g. occ to add the missing indices. Something seems wrong here with PHP Memory Limits. The following works fine:

docker exec nextcloud su - www-data -s /bin/bash -c 'php -d memory_limit=-1 -f /var/www/html/cron.php'

The PHP_MEMORY_LIMIT variable within the container seems to be set to 512. I found an older support-ticket regarding issues with this limit:
https://help.nextcloud.com/t/allowed-memory-size-of-xxx-bytes-exhausted/39371

So there seems an issue with the container's internal environment configuration.

Just do add some information. This is also happening with the latest 19.0-apache and 20.0-apache and can be easily reproduced with a fresh new container from these images.

Happens on latest PHP 7.4 and 8.0 too.

The PHP_MEMORY_LIMIT variable introduced with 061d860 is not set when running docker exec.

Possible fixes:

• docker exec nextcloud su - www-data -s /bin/bash -c 'PHP_MEMORY_LIMIT=512M php -f /var/www/html/cron.php'
• docker exec nextcloud su --whitelist-environment=PHP_MEMORY_LIMIT - www-data -s /bin/bash -c 'PHP_MEMORY_LIMIT=512M php -f /var/www/html/cron.php'
• Add PHP_MEMORY_LIMIT=512M to /etc/enviroment.

[pfaelzerchen]

The PHP_MEMORY_LIMIT variable introduced with 061d860 is not set when running docker exec.

To be precise: It is not set, if you make the user switch to www-data. So the following will give you nothing

$ sudo docker exec nextcloud su - www-data -s /bin/bash -c 'env' | grep PHP_MEMORY_LIMIT

Executing this with root privileges in the container, will show a PHP_MEMORY_LIMIT

$ sudo docker exec nextcloud /bin/bash -c 'env' | grep PHP_MEMORY_LIMIT
PHP_MEMORY_LIMIT=512M

The given fixes work for me. However, using the -d switch of php (-d memory_limit=-1) does not work with 512, but with -1.

The same happens on Arch Linux with nextcloud package. Creating the following file fixes the problem with occ:

# cat /etc/php7/conf.d/apcu.ini
[apcu]
apc.enable_cli=1

[ianhundere]

i'll chime in and ditto the fix of making PHP_MEMORY_LIMIT available as an env:
sudo -u www-data PHP_MEMORY_LIMIT=512M php -f cron.php

[Nowaker]

Adjusting the memory limit does not fix the issue. In my case 4 GB was not enough. People reported setting as high as 8 GB would not work for them. https://help.nextcloud.com/t/solved-occ-command-php-fatal-error-allowed-memory-size-of-xxx-bytes-exhausted/108521/11 Even 32 GB was mentioned but it wasn't clear to me the OP meant 32 GB is enough or not enough: https://help.nextcloud.com/t/solved-occ-command-php-fatal-error-allowed-memory-size-of-xxx-bytes-exhausted/108521/12

[ToeiRei]

@Nowaker do you use apcu? if yes, switch to redis as a memory cache.

For me it helped to set the user in in the Docker exec ommand:
docker exec -u 33 nextcloud php -f /var/www/html/cron.php
User 33 is www-data.

I'm running into this as well. While I'm running from docker as well, I'm not using the docker image provided by Nextcloud. Instead my setup is based on two fedora containers, one with apache, the other with php-fpm.

The default memory limit on my php installation is 1Gb. With the memory limit I still run into occ out of memory issues. I have tried to gradually increase the memory limit using -dmemory_limti=xyz. At 3Gb it's still breaking. With no memory limit (-1) occ will be killed by the OOM.

I have returned to nextcloud 20.0.11 until the real cause of this issue is found.

I had the same issue today, on my Ubuntu server.

When I tried running my cron.php:
docker exec nextcloud php -f /var/www/html/cron.php
I had:
PHP Fatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 20480 bytes) in /var/www/html/apps/files_trashbin/lib/Helper.php on line 85

I solved it simply by mapping a php.ini file in my docker-compose nextcloud's volumes like so:
- ${CONTAINER_FILES_ROOT_PATH}/nextcloud/php.ini:/usr/local/etc/php/php.ini
content:
PHP_MEMORY_LIMIT=1024M
I then restarted the nextcloud container and ran the cron.php once more. It then ran without the error.
I think the process just needed a bit more RAM since I have more and more files on my nextcloud server (a few Tos).

Hope this helps someone

hi,
I'm really new here, so I hope, everything works fine with me answer.

@ pfaelzerchen: I had nearly the same line:

Fatal error: Allowed memory size of 2097152 bytes exhausted (tried to allocate 438272 bytes) in /var/www/html/3rdparty/composer/autoload_real.php on line 37

only the size of the allocated bytes differed

My nextcloud doesn' t run in a docker, so I was astonished. Beside this line the cronjob of nextcloud (22.2.0) was not running.
What helped was:

set the memory_limit = 512M in /way/to/your/php/X.X/cli/php.ini
but set the memory_limit = -1 in /way/to/your/php/X.X/fpm/php.ini
